It won't play in VLC or MPC-HC64. I haven't tried a standalone player. Disk looks clean.

It's AACS v82. Your assistance would be appreciated. Thank you.

I believe you still have to attach the dump MakeMKV created to an email and send it to svq@makemkv.com. Eventually a hashed key will be produced and the disc will be able to be decrypted. With respect to MakeMKV, AACS v82 blu-rays operate very similarly as 4K UHDs.

In the mean time, you can try the public keydb, which is a separate key mechanism that MakeMKV can use.

Thank you. It's ripping fine with a different tool. I'll come back to makemkv the next time I hit v82.
